mittens-WHEEL Specification of Letters Patent.

Application filed March 6, 1909. Serial No. $81,75

Patented Apr. 5, Edit To all whom it may comer Be it known that l,Bonner G. Dustin),

citizen of the United States, residing at Detroit, county of Wayne,State of Michigan, have invented acertain new and useful Improvement inVehicle-Wheels, and declare the following to be a full, clear, and exactdescription of the same, such as will enable others skilled in the artto which it pertains to make and use the same, reference being had tothe accompanying drawings, which form a part of this specification.

My invention relates to an improvement in at type of vehicle wheels inwhich a heating Wheel is concentrically supported within an outer rim orwheel by a plurality of radially arranged helical springs connected atone end to the hub of the inner wheel. and at their op osite ends withthe encircling rim 01' wheel.

One of the objects of the present invention is so to construct andarrange the parts that helical springs of a greater length may beemployed on wheels of a given diameter than have heretofore beenpossible, thereby greatly increasing the resiliency oi X the springs andenlarging their usefulness as shock absorbers.

Another feature of the invention consists inasseinbling the springs inpairs, one on each side or" the floating wheel, by means of which theparts are more perfectly balanced.

Another feature is the ease with which a spring may be removedorinserted in the event of it being necessary to make repairs.

Other advantages and improvements will hereafter appear.

In the drawings accompanying this specifications-Figure 1 is sideelevation or" a wheel in which certain of the radiating springs havebeen removed in order to sh w those on the other side of the floatingwheel that lie in the same plane with those that have been removed. Fig.2 is a cross sectional View through. the wheel. on. line XX of Fig. 3.

Referring now to the letters reference spread upon the drawings :-A istheouter rim or wheel in which is mounted the tire B.

C is the telly of the floating wheel.

D are its spokes, and E is its hub having a project ng flange E integraltherewith.

E is an annular disk mounted on the hub E and between the flange E, andsaid disk E are secured the inner ends of the spokes D. Projecting fromthe side of the flange 1C and also from the disk E are annular rims cintegral therewith, both being perforated to receive the bolts employedto socure the ends of the helical springs G to the hub.

c is a projecting rim formed at or near the periphery of the flange Eand c is a similar rim formed at or near the periphery .ot the annulardisk E These rims are provided with depressions c for the passage of thesprings G,the purpose being to partially embrace the helical springs andthus relieve the strain on the bolts 9 that secure the spnings to thehub portion. It will be readily understood that otherwise the strain dueto any slight rotary movement of the floating wheel would be directlyupon the attachment to the outer rim A, springs ot' greater length maybe employedthereby increasing their efficiency as shock absorbers. Ifind, however, that the construction shown is adapted to receive springsof sul'iicient length to attord the proper amount of resiliency.

Having thus describedmy invention, what I claim is 1. in vehicle wheel,a hub portion, an-

' carried by the hub portion, concentric rim spaced from flty of yokessecured to the A A g the telly, the side walls provided at substantiallymidends with projecting lugs adapted to receive the ends of springs, aplurality of springs each respectively secured at one end to one of theannular rims of the hub portion, each spring extending beyond the closedend of the yokes and secured at their opposite ends respectively to thelugs of the several yokes.

2. In a vehicle wheel, a hub portion, an

annular rim carried by the hub portion, a

r and res ectivel secured to the oro'ectin 1. D

a the telly, a plurality of yokes spaced from and embracing the telly,each of their side felly, a concentric rim spaced from the telly, aplurality of yokes secured to the rim and encircling the telly, saidyokes having projecting lugs on each of their side arms mid- I Way theirlen th, and a plurality of springs arranged in pairs one on each side ofthe telly, their inner ends being secured to the rim of the hub portion,their outer ends extending beyond the closed ends of the yolres lugs ofthe several yolres.

8. In a vehicle wheel, a hub portion, an annular rim supported by thehub portion, a telly, a rim spaced from and concentric to arms providedwith projecting lugs spaced midway of their length, a plurality of,springs secured at one end to the annular rim and at their respectiveopposite ends secured to the lugs of the several yolres, and I anannular rim concentric to the first named rnnprovided with depressionsto partlally receive the springs lying in said depressions.

4. In a vehicle Wheel ahub portion, an annular rim supported hy the hubportion, a telly, a rim spaced from and concentric to the telly, thelast named rim and embracing the telly, a plurality of springs securedat one endto the annular rim and at their respective 0pposite endssecured to each of the several okes,- and an outer annular rimconcentric to the, first named rim provided with depressions topartially receive the springs lying in said depressions. i

In testimony whereof, l sign this specification in the presence of twoWitnesses.
